Continuity mistake: The leather strap around Manolito's neck is sticking prominently up out of his shirt collar in all the over-the-shoulder shots, but it disappears every time the angle reverses to a frontal view.

While shooting an early episode, Henry Darrow fell from his horse and suffered a painful bruise when he landed very hard on the gun at his hip. After much pleading, he convinced the producers and the prop dept. to make a replica pistol out of rubber. Replaced by the real one only when it actually had to be fired, the fake gun remained in Manolito's holster for the rest of the show's run.
